Confused on how to find the mass of player 2. two hockey players are traveling at velocities of v1 = 13 m/s and v2 = -17 m/s when they undergo a head-on collision. after the collision, they grab each other and slide away together with a velocity of -3.5 m/s. hockey player 1 has a mass of 122 kg. what is the mass of the other player? you.

here in this type of collision we can use momentum conservation

here we know that

now by above equation of momentum conservation

so mass of the player 2 will be approx 149 kg

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
